It could be argued that we're all "a piece of work" but thats besides the point and I digress. My apologies if I offended you
My point merely being that in the 20 minutes between first post and answer had you had your book it would have been answered. I was of course assuming you were in proximity to your car, as very few enthusiasts don't have their manual with their vehicle for emergency answers. Failing that, there's the PDF manual on this very site. Its answered most of my questions and I'm not even an owner yet.
